When a guy asks like this, what does it mean?

Me and this guy have been talking for a little over two weeks now. He's complimented my musical abilities, we've swapped videos of each other singing, and he seemed to take an interest in my life. He posted on a group Facebook page there's a concert next week, so I brought it up to him, and he said "Yeah, you should def come!" I'm going to be the only girl there, and he sent me a Youtube video of the band. Long story short, I told him to keep me updated on car pooling plans, and he said he would keep me posted and asked for my number... Does this mean anything?
